Weld nipple with O-ring seal, tube 38 x 5 mm, phosphated steel

Once installed, the weld nipple joins a precision steel tube to the coupling by a weld seam and seals with an O-ring. The data sheet gives a working pressure of 315 bar. This version is listed with tube diameter by wall thickness 38 x 5 mm. Material phosphated steel is listed for this version.

Benefits

• The weld seam on the 38 x 5 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 38 x 5 mm matches the 315 bar rating.
• The soft-sealing joint can be undone without touching the weld seam.
• The temperature range covers -35 to +100 °C.
• The version in phosphated steel sets the corrosion protection and the suitability for welding.
